Top soccer players do not necessarily have an extraordinary capacity in any of
the areas of physical performance. Soccer training is largely based on the game
itself, and a common recruitment pattern from player to coach and manager
reinforces this tradition. New developments in understanding adaptive processes
to the circulatory system and endurance performance as well as nerve and muscle
adaptations to training and performance have given rise to more effective training
interventions. Endurance interval training using an intensity at 90–95% of maximal
heart rate in 3- to 8-minute bouts have proved to be effective in the
development of endurance, and for performance improvements in soccer play.
Strength training using high loads, few repetitions and maximal mobilisation of
force in the concentric mode have proved to be effective in the development of
strength and related parameters. The new developments in physical training have
important implications for the success of soccer players. The challenge both for
coaches and players is to act upon the new developments and change existing
training practice.
